I have a galaxy S 4 for Cricket model SCH-R970C. I need to unlock the phone to able to use the SIM slot outside the U.S. I've been able to root the phone and I tried flashing a i9505 ROM thinking that would unlock the use of the SIM with no luck. The baseband modem firmware does not change when I flash a different ROM. There is little to no info out there about the cricket GS4. Is it possible to flash different modem firmware so that the phone can behave as an i9505 model? The hardware is the same... just can't change the modem firmware.
I need this ASAP otherwise I need to find a new phone! I'm not in the US now and calling Cricket is not an option. I tried flashing a different modem firmware using ODIN but it fails. What am I missing?
Any help would be appreciated. I'm willing to "donate" $$ for a solution. Thanks.

Hi,
You should not flash a modem that is not meant for your phone.
You are risking a brick if you try it.
Your best bet may be to just buy an unlock code online.

No, i gave up on the phone. I don't think it's that easy to change the baseband firmware on the phone. I didn't try buying an unlock code, but that might be the only solution for now - just make sure the unlock code is specifically for the cricket model.
Has any managed unlock it? I need older modems in order to complete. The unlocking please provide me with them if you have.

I doubt it. It's not made for your model so chances are it won't flash or won't work. Try using RegionLock Away or finding your phone's older firmware on sammobile and extracting the modem with 7zip and ext2explore.
Hello, I can't seem to find the perfect answer in another thread.. I'm on a google experience 4.4.2 rom, with the MK6 modem and i'd really like to unlock my phone for use on a different carrier. i tried flashing an older modem but no luck.. is there a way i can do this myself without going into a shop and paying $40?
Hi guys one of my friends bought a S4 in the US, It's AT&T locked SGH-I337 so can't use it with sim in our country (South Africa)We have two models of S4 here, the I9500&I9505. Was wondering what the right steps is to get the phone working? Must I root the phone and flash custom Rom & kernel or just unlock sim card? I'm not new to Rooting or flashing Roms but haven't fidled with carrier locked phones before. And is it possible to use custom Roms from At&t in other countries thanks in advance [emoji2]

The Sgh-i337 is basically the same as the gt-i9505 EXCEPT for ATT locking the bootloader on that model.
You CAN Sim unlock it so you can insert your Sim into it. You will have to reach it a bit though. It helps if you know what firmware is installed on the phone. If it is MDB, MDL, or MF3 it would be easier to do I believe. Either way look for the threads about unlocking.
If you have NEWER firmware then there are separate threads for it, and it will more than likely need to be rooted, flash a older modem, then perform the Sim unlock from the menu. If you cannot find the correct post I can help look for it later.
Just reply back with WHAT firmware and Baseband you have installed on the phone and we should be able to help you further.
If you do have MDB or MDL firmware do NOF update it...

Thanks for reply ,I have NC1 firmware and I used Method 3 on this guide http://forum.xda-developers.com/showthread.php?t=2595457 .SUCCESS!
Could you recommend a modem I could try other than MF3 as the signal isn't that great ?

Not sure which would work best for your area. You can download and try any/all of them until you find one that works best. You can switch back and forth with no issues without worries
Im using a 900v on ATT, rooted, all is well with that, BUT I would like to ask if anyone can steer me straight on what modem I can flash?
Being it's a Verizon phone I'm scared lol jk
So anyone willing to help?
You need to flash the modem / firmware for your phone, the G900V. Don't try and flash firmware from other variants.
Can I flash another firmware like tmobile or att on my s7 sprint ??? And how can I do that
Sorry for the noob question
Nobody knows about it???
if you have the actual "Sprint" sm-g930p, then your answer is yes as long as it's unlocked. well you can flash even if it's not unlocked, but if it isn't then you won't be able to connect to whoever your carrier is because the device will be sim/network locked to the original carrier. But honestly why flash any other carriers firmware when just simply flashing the "sm-g930u" firmware will pretty much give you all APN access and you can then connect to whoever your sim supports, with no carrier bloatware. Fully functional... Half the crap.. lol .. and a simple Odin flash should do the trick. use either prince's, or the newest build 3.12.7 i believe.. I've been using only that one and have rooted, flashed dif firmware and even tinkered with some bootloader ideas (unsuccessful) and was able to use the same odin for all.
